WDSU first reported last week that detectives intend to present evidence that may lead to the first charges in the matter. It is likely, they said, that those charges would be desecration of a corpse, and not murder.

They expressed concern that filing any murder charges prematurely could hurt chances for convictions on those most serious counts.

Two individuals -- Terry Speaks and Margaret Sanchez -- were linked to Lockhart early in the investigation, but neither was charged. Speaks, a convicted sex offender, is currently serving time in an out-of-state federal prison.

The duo are seen on surveillance video taken at a Bourbon Street men's club days before Lockhart's remains were discovered.

Don Bass, the chief deputy of the Hancock County Sheriff's Department, said investigators aren't sure where Lockhart was killed. Her remains washed ashore on a beach within his department's jurisdiction.

Bass said investigators hope the material they share with prosecutors will be presented to a grand jury. He says an indictment would allow authorities to hold the two while the investigation continues.
